To all? whom it may concern.-

vBe it known that I, ALBERT P. BROME'LL', of York, in the county of York and State of Pennsylvania, have invented a new and useful Improvement in Steam Heating Apparatus, of which the following is a' specilication My invention is an improvement in steam heating apparatus having for an object to provide, first, a steam-heating system by which it is possible to regulate the amount of steam admitted to each radiator and to heat eachY radiator all or part of the way over, as re-v quired; second, a system in which all radiators are open to the atmosphere, the heating being laccomplished by the circulation of stean without pressure through the radiators; third, a system in which no air-valves are required o`n the radiatorsg fourth, a system in which it is impossible for water to accumulate in the radiators; fifth, a system th'at will work absolutely noiseless; sixth, a system that can be installed with the use of much smaller pipes than ordinarily used, and, seventh, a system in which are provided means whereby the production of steam in excess of the demand will control the damper of the boiler-furnace and will further automatically operate relief devices, whereby the water of condensation will be returned to the boiler, whereby the shutting off of steam from the radiators will automatically open a vent from such radiators to the atmosphere.

The invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a sectional ele-v vation of a building presenting in somewhat diagrammatic form a heating apparatus embodying my improvements. Fig. 2 is an elevation of the boiler and parts directly associated therewith. Fig. 3 is a side view, partly broken away in section, of a receiver provided with my improvements. Fig. 4 is a cross-section on about line 4 4 of Fig. 3, and Fig. 5 is an end View of the radiator feed-valve. Fig. 6 is a vertical longitudinal section. Fig. 7 is a top plan view, and Fig. 8 a horizontal section, of the radiator-valve.

The boiler A may be of any suitable form of steam-heating boiler, preferably one having a low water-line. The steam supply pipe or feed pipe B is connected ordinarily at the vbut not necessarily, at the top thereof. A `feed-pi es connect with the radiators through usual point of outlet of the boiler and is eX', tended in snitabledirections and connected by branch pipes C with the heating-radiators D, connecting with such radiator, preferaily,

the me ium of the valves (Shown in Fig '1 and lin dean in Figs. ,5 to s, inciusivei This valve Eis designed to admit any desired amount of steam to the radiator and will be morefully describedhereinafter. I I

The return-pipes F lead from the radiator back to whatl term the z receiver, G. The receiver G is shown in detail in Figs. 3 and 4, and in practice is arranged above the watersteam-space thereof. As' shown in Figs..

and 2, I form the receiver preferably with glass sides G', so its interior is enpose'd to View, and it is connectedA by a pipe G2 with the boiler below the water-line of the latter and is supplied with a gage G3 to indicate by the height of water the pressure in the boiler, graduations being provided on the pipe G2 or otherwise to indicate the degree of pressure of steam by the height of water in the said pipe.

.line of the boiler and preferably above-th At its top the receiver Gis provided with `openings F for the return-pipes F and with an opening H for the waste-pipe H, leading to the condensing-radiator I. The bottom ofthe receiver is tapped 'for the connection of the pipe G2 and also to receive the reliefpipe J, which opens into the steam-space of the boiler. The pipe J is extended within the receiver and has its upper or discharge end arranged above the normal water-line in the receiver. .This pipe .I is controlled by the safety or relief valve K, provided with and arranged for operation by the iioat K', which float is arranged in the receiver Gand for operation by any excessive rise of water in said receiver.

The float L operates in the receiver G and is carried on an arm or lever L' on a shaft L2, carried through a stuffing-box L3, and having an arm L4, connected by chain L5 with a damper M, which regulates the fire in the steamboiler furnace. When the water rises in the receiver G, it will lift the float L, which movement of the float closes the damper to a degree relative to the height to which the float L' may risc, the damper moving gradually IOO toward closed position until it is entirely shut. If the water continues to rise in the receiverafter the damper Mis shut, the reliefvalve will be opened by the rise of its float and the pressure in the boiler will be relieved in the manner more fully described hereinafter.

The con(lensing-radiators I, ol' which there may be any desired number, are connected by a pipe H with the receiver and by a pipe 1I with a condensing head or drum T, placed in the attic or above the roof or otherwise suitably located.

The boiler has a glass gage Aio indicate the height of the water within it.

Vhen no steam-pressure is on the boiler, the water in the glass gage A/ on the boiler and in the glass gage G", attached to the receiver G, will stand at the same level. After re is made in the boiler and steam gener-A ated and before any appreciable pressure is produced the steam will pass out through the main supply-pipe and will be discharged into the radiators in such quantities as the valves E will permit. After the radiators are heated from end to end should there be any steam escaping back through the returnpipes F this steam will be discharged into the receiver, and from this receiver the surplus steam thus discharged will pass into the condensing-radiator, where it will be condensed into water and returned to the receiver, from which point it will, ot' course, return to the boiler. Il' there is sufficient ire in the boiler to produce a pressure, it will naturally prevent the water of condensation from returning to the boiler until this water has accumulated in the pipe leading from the receiver to the boiler to a suliicient height to overcome the equilibrium, when it will [low into the boiler by gravity.

In the event of suilicient pressure accumulating in the boiler to lift the water into the body of the receiver the water will come in contact with float L and will lift this float, and as soon as the float L is moved upward the damper M will begin to close,\vhich movement will continue until the damper is ent-irely shut. If steam continues to increase in pressure after the damper is shut, the water will continue to rise in the receiver G until it reaches the float K', attached to the relief-valve K, and will lift the relief-valve from its seat, discharging steam from the steamspace in the boiler into the receiver, from which point it will pass through the pipe II on top of the receiver G into the condensingradiator I above. In the event of the condensing-radiatornothavingsuflicicnt surface to condense all the steam thatmay discharge into it from the relief-valve thc surplus steam will pass up the pipe II', connected to the top of the condensing-radiator, and into the condensing-head I, the surface in which condensing-head will be ample to condense all steam that may reach that point.

The valve E is so constructed as to ad mit .O and its spring and handle devices.

steam to any desired degree to the radiator and to open a vent to the atmosphere when it is adjusted to entirely cut oit steam from the radiator. B y this valve any desired qualitity of steam can be admitted to the radiator, heating the radiator to such a degree as may be necessary to warm the room in which itis placed and making it possible to regulate the temperature ot the room to any desired point. As the radiators are open to the atmosphere through the return-pipes and the condensingradiator, they do not require any air-valves, and the radiators also being open to the at- Arnosphere makes it possible to circulate steam through them without any pressure on the4 boiler, and there will be no possibility of-water accumulating in the radiators. The construction of the valves Eis best shown in Figs. 5 to 8, incl usivc. The valve includes the casing, having a head E", provided with a series of sockets i2 for the stop-pin and an opening E3 for the valve-stem, the seat E4 having feed-ports l, 2, 3, and 4.- for the steam andan air-port 5 for communication with the atmos- )here ni les 6 and 7 for connection res ec- I i D tively with the steam-feed pipe and with the radiator, the valve proper, N, having a noncireularsocket O for the stem O, and the stem valve N lits 011 the seat E" and is provided with the series of ports N" N2 N3 N4, which vmay be turned to register, respectively, with ports 1, 2, 3, and et when the valve is fully opened or to open any desired ones of the said ports 1, 2, 3, and 4 to any desired degree. \Vhen the valve is in the position shown in Fig. S, the steam-ports 1, 2, 8, and 4 are closed andthe port N is in full register with the port 5, opening communication with the atmosphere, breaking the vacuum, and preventing a suction of water from the returnpipe. This is the position of the valve shown in Figs. G and S. It' now the valve be moved one point to the right, the port N1 will register with and open the feed-port l, the air-port 5 will be closed, and steam will be fed through the port 1 to the radiator. Another step of the valve will open ports 1 and 2, and so on, until the full head of steam is admitted.

The stem O fits atits lowerendin the socket O and extends upward through an opening O2 in the head-plate E', being provided beneath said plate with a packing portion or shoulder O and with a spring O, bearing between the same and the valve-plate and operating to press the valve to its scat and the portion O3 tightly up against the head-plate E. On the stem above the head-plate I secure the arm P, having near its outer end the handle P', which has a limited longitudinal movement in the arm and has the stop-pin P2,

which can be set into any 011e of the sockets E2 to hold the valve in any desired adjustment. The outer end of the arm P is socketed and receives a screw P3, by which the handle can be locked in any one of the sockets E", and a cross-pin P1 limits the upward The IOC

esoffrs movement of the handle and prevents its being pulled out of the arm P. The operation of the valve will be readily understood from the foregoing.

My system permits the use of much smaller supply and return pipes than those ordinarily employed.

In the event of the fire being neglected and too much steam-pressure being produced there is no possibility of Vlow Water in the boiler, since even if the safety-valve should blow for a long while the water will all be condensed in the condensing-radiator and condensing-head and will return to the boiler by gravity, keeping the proper water-supply in the boiler at all times.

The valve illustrated in Figs. 5, 6, '7, and 8 forms the subject-matter of a separate application for patent, Serial No. 9,275,iiled in the United States Patent Ottice March 19, 1900.
